Authoritarianism Through Coding: Signal This isn’t a theoretical piece about freedom and digital technologies. This is a real ongoing trend that is at best observed around secure messaging application Signal by Open Whisper Systems and it’s founder Moxie Marlinspike. His view and management of Signal reflects a wider trend that jepordises world’s freedom. Signal is a secure messaging software that has changed the field a lot. Signal is built upon propriety software Textsecure and RedPhone applications that had been developed by Marlinspike and his co-founder Stuart Anderson. When Twitter acquired Whisper Systems, it releases both software under free software licenses. Marlinspike left Twitter acquired Whisper Systems, founded Open Whisper Systems and merged -once the private property of himself- TextSecure and Redphone into Signal.
